The Clarity of the stone refers to the relative freedom from inclusions, these are characteristics that can be seen within the stone that were there when the stone formed in nature up to 350 million years ago. Different factors determine a stones clarity grade for example; number of inclusions, size of inclusions, position, brightness and nature/type. The best stones are Flawless (F) and the "worst" are 'Included (I) or otherwise politely termed Pique (PK).

The Cut of the diamond is the lowest grade of; Proportions, Symmetry and Polish. A badly proportioned stone will not allow total internal reflection of light and will not be as bright (sparkle). There are excepted ranges of proportions and as long as the stone is within these it will look beautiful. Symmetry basically means how well all the facets (individual cuts) are aligned and Polish tells us how well the facets have been cut by polishing lines or burn marks.

Some stones fluoresce under Long Wave UV light. Since UV light is an integral part of daylight, a level of fluorescence within the stone can affect the colour of a stone or make its appearance more colourless when it is tined. The grading system runs from None down to Strong. Most diamonds tends to fluoresce blue under this light.

Carat is the weight of the stone. With a well cut stone the carat weight can give an estimate of size (mm). 1 carat is the equivalent of 0.2g. And with a well cut 1ct stone it should be 6.5mm diameter (for Diamond). This is considered a large stone. Some stones have a larger spread, what we mean by this is they have a larger surface area/diameter but will be shallow.
